Abstract
The invention relates to an air pressure rod. The air pressure rod comprises an outer pipe and a stretching rod penetrating through the inner and outer sides of a first end wall of the outer pipe in the axial direction. A fixed seat is fixedly arranged in the outer pipe, and a valve cock penetrates through a passage of the fixed seat. An inner pipe with a hollow containing chamber is arranged near the fixed seat in the axial direction. A piston rod of the stretching rod abuts against the inner edge of the inner pipe. The inner pipe made of plastics integrally extends from the fixed seat made of plastics, and an annular wall extends from the edge of a passage of the fixed seat, so that the length of the passage is increased. The air pressure rod has the beneficial effects that by means of the design, the connecting seams of the components of the air pressure rod are greatly reduced, the possibility of air leakage in the air pressure rod is reduced, the contact area of the valve cock and the passage is increased, and the leakage blocking effect of the valve cock is improved.
Description
Technical field
The present invention is about a kind of pressure rod, espespecially a kind of as buffering and the pressure rod regulating height.
Background technique
Pressure rod mainly utilizes gas upset condition that compression process produces in earthen pipe, can be widely used in the utensil needing height adjustment, such as but not limited to chair tool.

Embodiment
Below by graphic auxiliary, structure, feature and embodiment that the present invention invents are described, in order to do making your audit crew the present invention are invented to have and further understand.
Refer to Fig. 3, coordinate shown in Fig. 1 and Fig. 2, the present invention, about a kind of pressure rod, comprises an outer tube 1, and this outer tube 1 two end is respectively equipped with one first end wall 11 and one second end wall 12 (for show stereo decomposing, this first end wall is not yet bent to form Fig. 1); This second end wall 12 wears a pressing member 31, is provided with a baffle ring 121 and prevents this pressing member 31 from coming off in order to form clip with this pressing member 31 inside this second end wall 12;
Axially be separated by inwardly with this pressing member 31 and establish a bibcock 32, this bibcock 32 stage casing is provided with a narrower cervical part of esophagus 321, and this cervical part of esophagus 321 is the use for the ease of gas circulation; This bibcock 32 is provided with resistance and lets out ring (322) in order to prevent Leakage Gas.
This bibcock 32 is arranged in the duct 33 that is fixedly arranged on the fixed base 3 in this outer tube 1, and this fixed base 3 periphery is also provided with two or more resistance and lets out ring 30 to prevent gas in this pressure rod via the joint leak between this fixed base 3 and this outer tube 1; Axially adjacently with this fixed base 3 establish one to have pipe 4 in medium altitude chamber 40, this medium altitude chamber 40 communicates with this duct 33; Inner tube wall 41 towards this fixed base 3 be provided with one communicate with this duct 33 first export 401, this bibcock 32 compresses and reply and open and close this duct 33 and open and close this and first export 401 for this pressing member 31 operability; This interior pipe 4 tube wall is provided with first import 402 communicated with this medium altitude chamber 40, and this interior pipe 4 tube wall outer side surface is provided with first air flue 403 all communicated with this first import, outlet (402,401).This pressure rod comprises an axial flexible rod 2 be extended through inside and outside this outer tube 1 first end wall 11, and this flexible rod 2 is closely butted on this interior pipe 4 inner edge with a piston piece 21.This part belongs to general technology, therefore appearance does not repeat its detailed configuration and operating state.
Be provided with one first pad 111 inside this first end wall 11, be provided with a soft tough and yielding resistance and let out block 112 inside this first pad 111, this resistance is let out inside block 112 and is established one second pad 113.This resistance lets out block 112 under the action of axial air pressure and this first end wall 11 clipping mutually, extends amount of deformation toward radial direction, and is formed with this outer tube 1 and this flexible rod 2 simultaneously and fit tightly, and prevents the Leakage Gas in this pressure rod.
This interior pipe 4 of plastic material of the present invention is extended by this fixed base 3 one of plastic material, and this fixed base 3 extends a ring wall 34 in this edge, duct 33, to make this duct 33 extension.Because this fixed base 3 is integrally formed with this interior pipe 4, makes the component in this pressure rod connect gap and significantly reduce, and then the chance of the Leakage Gas in pressure rod is significantly reduced.And because the number of components reduces, also make the assembly program of this pressure rod significantly simplify; Because this fixed base 3 and this interior pipe 4 are plastic material, therefore when manufacturing this fixed base 3 and this interior pipe 4 and inside and outside passage thereof or conduit (as this duct 33, this medium altitude chamber 40, holding conduit, this first air flue 403 etc. that ring 30 is let out in this resistance), namely can complete via one injection molding, do not need other processing, significantly increase and manufacture convenience.Even if there is necessity (as boring, cutting etc.) of processing, its processing convenience is also because it is plastic material and significantly promoting; Except being convenient to be shaped, to process and assembling, this fixed base 3 and this interior pipe 4 of plastic material also do not affect the anxiety of this pressure rod action effect because corrosion is rotten.
In addition, this fixed base 3 extends a ring wall 34, to make the extension in this duct 33 in this edge, duct 33.This design makes the area of contact between this bibcock 32 and this duct 33 increase, and makes this bibcock 32 more can set up two or more resistance letting out ring 322, and then makes this bibcock 32 can form better resistance in this duct 33 to let out effect.
In a preferred embodiment, this fixed base 3 is more provided with one second outlet 401A, this interior pipe 4 tube wall is more provided with one second import 402A, and this interior pipe 4 tube wall outer side surface is more provided with a second air flue 403A all communicated with this second import, outlet (402A, 401A), can air mass flow be expanded whereby, make the rising or falling speed of this pressure rod very fast.
Please coordinate shown in Fig. 4, in a preferred embodiment, this first air flue 403 along this interior pipe 4 outer side surface in the shape of a spiral, to extend the length of air-flow path in a limited space, and permanent use under do not affect the out of roughness of this medium altitude chamber 40 cross section of this interior pipe 4.
Refer to Fig. 5, coordinate shown in Fig. 6, in a preferred embodiment, this first air flue 403 is linearly along the outer side surface of this interior pipe 4, as shown in the figure, this interior pipe 4 tube wall outer side surface more can be provided with the linearly air flue of two or more (403A, 403B, 403C), and this two or more air flue (403,403A, 403B, 403C) arranges radially along these interior pipe 4 outer periphery, increase the capacity of air-flow channel whereby, and do not affect the out of roughness of this medium altitude chamber 40 cross section of this interior pipe 4 under permanent use.As shown in Figure 6, this two or more air flue (403,403A, 403B, 403C) by after this interior pipe 4 outer edge cross-section is cut into polygonal, can be connected to this outer tube 1 and is formed.
Above-described embodiment is only for the invention example is clearly described, and the restriction not to the invention embodiment.In order to the combination relation of each parts is clearly described, carry out usually describing around its function to various illustrative parts and annexation thereof above, combination as this parts realizes which kind of function, the design constraint depending on specific application and apply whole device.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.All within the spirit and principles in the present invention any apparent change of extending out or variation be still among the protection domain of this claim.
